Synthesis and properties of tetrathiafulvalenes bearing 6-aryl-1,4-dithiafulvenes

Novel multistage redox tetrathiafulvalenes (TTFs) bearing 6-aryl-1,4-dithiafulvene moieties were synthesized by palladium-catalyzed direct C–H arylation. In the presence of a catalytic amount of Pd(OAc)(2), P(t-Bu(3))·HBF(4), and an excess of Cs(2)CO(3), the C–H arylation of TTF with several aryl br...

Sumario:Novel multistage redox tetrathiafulvalenes (TTFs) bearing 6-aryl-1,4-dithiafulvene moieties were synthesized by palladium-catalyzed direct C–H arylation. In the presence of a catalytic amount of Pd(OAc)(2), P(t-Bu(3))·HBF(4), and an excess of Cs(2)CO(3), the C–H arylation of TTF with several aryl bromides bearing 1,3-dithiol-2-ylidenes took place efficiently to produce the corresponding π-conjugated molecules. We also succeeded in the estimation of the oxidation potentials and number of electrons involved in each oxidation step of the obtained compounds by digital simulations.
